j o all whom it may concern:

lie it known that l, Fnnnnnreig Sanering, a citizen et the United States, residing at Ghi-v cago, in the county of Cook and State of illinois, have invented certain new and useu iul improvements in Cars, of which the following is a specification.

The object of my invention is to provide an. improved operating mechanism for the doors ot dump cars.- it is especially designed tor use in that class of dumpcars in which there is a horizontal 'floorI and in which the lgreater part of said floor consists of doors hinged at or near the longitudinal center line otl the car. The doors are hinged in such manner as to allow the outer edges `beneath the side walls of the car to drop and discharge the contents outside the track. lily improvements are applicable, however, to other forms of dump cars. l

lily improvements comprise toothed bars or racks pivotally attached to the outer corners ot the doors and operated by a pinion on an operating shaft lying adjacent t the outer edges of the dump doors. This operating shattis worked by a hand lever and ratchet mechanism at the end of the car.

Another feature of my improvements isv a toothedmexnber carried by the doors for holding them in a closed position which is operated by the same pinion that actuates the toothed bar or rack. This toothed member is preferably pivoted to the doors and may be moved into engagement with a pin` or othersuitable part of the car `frame. lll] hen thus engaged, it relieves the toothed lbar or rack and otherparts of the mecha nism of strain.

@ther and'further objects of my invention will be made apparent in the following description and claims, taken in connection with the accompanying drawings, in whichf'` Figure 1 is a side elevation of a dump car with my improvements attached.v Fig. 2. is

Fig. 14 is a perspective view of one of the gears. Fig. 15 is a sec-- tion through the o'uteredge of the door and its connections to the operating mechanism. Fig. 16 is a section through the outer edge of the door, showing a modification in its connections to the operating mechanism. Fig. 17 is a side elevation of the same.

` in 'the drawings, the side walls 10 of the car body are iixed` to the side sill`\11, preterably made of an angle bar. The side sill 11 and side lwall 10 are supported by the transverse sills 12, which comprise the vertical webs or plates 12a and angle bars 13. The transverse sills are supported at the cen-ter of the car by a longitudinal center sill 14 to which they are rigidly attached. Connection is made between the side walls 10 and the transverse sillsA 1Q by the side stakes 15 which rise from the outer extremi ties of the transverse sills. The side'stakes are of hollow rectangular form in cross section, and are, preferably, made of sheet or plate metal formed into shape. They are formed with one side open, as seen at 1 6, and are provided with flanges 17 by which they are riveted to the wall plates 10 of the car body.` rlhe wall plates 10 serve as one side of therectangular hollow body iof the side stake. At or near the lower end ofv the side stake a 'lug or flange 18v is made by wall of the side stake, as shown in Fig. 12.-

.. This lugv or flange 18 is horizontally disposed and is placed upon and riveted to the angle bars 13 of the transverse sills 12. The downwardly extending-*side walls 20 of the side stakes 15 are riveted at their lower extremities 19 te the saine angle bars 13. The angle bars 13 are placed with their vertical legsv in Contact 'with and ixed to the` their lengt-h, but. are spread apart near their web or plates 12 in the greater part of as shown at 21, and is beveled at its end.-

The purpose of this construction is to give room for the mechanism to be'descrihed for operating the dump doors. Thls mechanism requires free access to the lower end of n the side stake 15.`

The dump doors 22-are pivoted at 23 to the centersill 14. The lateral edges 24 arebent downwardly at right angles to the body of the door to lorm stiifening and strengthguided by the wings ening tl anges.

The lateral edges of the doors lie 'beneath the horizontally .leg of the angle bars-'13.l The outer edge 25 .lies beneath the lower edge of the side wall 10 and thmside sill 11. A stiffening and i strengthening angle bar 2G is fixed to the under side of the door near its outer edge. There is a series of dump doors 22 on each side of the center sill 14, alternately arranged with transverse sills 12 in the dump cars for which my improvements are chiey designed.` The door 22 is held in a closed position by mechanism attached at the outer corners by means of the sleeves 30 having flanges 31 by which they are riveted to the angle bars 2G. The sleeves 30 on adjacent doors are connected by the bar 32 loose in said sleeves. This bar.32 may be of sullicient length to extend through the sleeves` 30 on adjacent doors only, as shown in Figs. 5 and G, or it may be a long bar extending through all the side of the car in hallc the length of said car. These long bars are shown at 32a in Figs'l and 17..

Fixed to the bars the rack bars 34 which have an eye 35 at their lower ends by which they are attached to the bars 32 or 321. At their upper ends;l they have laterally projecting lugs 3G which bear upon the inner faces of the walls of the hollow side stake 15, and are thereby guided centrally in said stakes. They are further 37 of vthe pieces 38 which are lixed' to 'the inner walls of the side stakes. rlhc teeth 39 of the rack bars' 34 are designed to mesh with the pinions 40 on the operating shaft 41. It will be seen that a rotation of thepinions 40 in one direction will cause the rack bars' 34 to rise and ull the doors 22 upwardly to a elose'dposition. When the pinions are rotated in the opposite direction, or left free to rotate, the rack bars 434 will be drawn downwardly by the weight of the doors. This downward moveyment will be limited by engagement of the laterally projecting lugs 36 with the'wings 37 of the pieces 38'. The pinionsl() are mounted upon the shaft 41 by means 'of interposed collars or sleeves 42 which are. fixed to the shaft by means o the pins 43. The

and the said polygonal connections.

disposed As the eye 35 'of the sleeves of the doors on one o2 or 32fL by pins 33 are e Lossless sockets 44 which receive polygonal exten.i

sions 45 of the sleeves 42. These polygonal sockets and extensions are preferably Octagonal, as shown most clearly in Figs. 13 and 14. The operating shaft will, of course, drive the pinions by means of the sleeves 42 The sleeves 42 are fitted into apertures 45 in the walls of the side stakes 15 which serve as bearings for them.

The doors 22 are held in a closed position by pivoted members 50 which have theV general form of a hook. These members 50 are loosely mounted upon the bars 32 or 32, and are recessed in their body portions at 51 to receive the eye 35 of the rack bar 34. rack bar is lixed to the bars 32 or 32 by a pin 33, the members '50 are held against sliding along said bars and are kept in a central position with reference to the stakes 15. The pivoted members or hooks 50 are provided with a hook shaped arm 52 having teeth forming a segment of a gear whose-axis coincides with that of theI hole 54 onwhichit is pivoted. The teeth 5.3 are adapted to mesh with the teeth of the pinion 40. The recess 51 is of such :form that the member or hook 50 will have a limited movement about its pivot. The Inovement is limited in an outward direction by the cross piece or rib 55 which comes in contact with the back of the rack bar 34. The movement is limited to such an extent that Athe first tooth 53 will not leave the pinion 40 while the door 22 is closed. The hook shaped arm 52 is designed to pass over the pin 56 fixed in the transverse sill at the base of the side stake. It is lmoved upwardly and inwardly by the pinion 40 `until the pin 5G limits the movement. In this position the doors 22 are held closed very el'ectually' and can beopened only when the pinion 40 is rotated in the opposite direction sufficiently to release the hook shaped arm 52 from the pin 56. The teeth 39 on the rack bar 34 are so placed that the lowermost tooth of said rack leaves the pinion b40 at themoment the arm52 begins to Ibear upon the in 5G when it is being rotated inwardly y the pinion 40. The rotation of the pinion 40 cannot then cause a further upward pressure on the rack bar, and thus cause damage. The uppermost tooth 53a is designed to come into full mesh witlrthe teeth of the pinion 40 at the i-nstant the door 22 is closed. Further movement of the pinion at that instant will cause the hook 52 to be rotated inwardly, but will not produce a further upward movement of the rack bar 34. A rotation of the pinion in ank opposite direction willl causethe hook 52 to be drawn awaypfrom the pin 5 6 and when it is: disengaged therefrom the uppermostatooth 53 will leave the .pinion 40. At
